McBSP ,EDMA and ST-BUS on C6711DSK

Started by active9009 November 25, 2004


Hi All,

I have a problem for initialize McBSP to interface with ST-BUS(4
channels); that is time slot miss-align, two slot are shifted.

My McBSP is serviced by EDMA and I've verified that EDMA transfer from
DRR is correct but transfer to DXR makes this problem. I've been solving
this problem but it still not work correctly. Anyone who have this
experience pls help me .

Thank you in advance

Tumm
